T-Mobile ER081 Error: What is it?

T- Mobile supports Wi-Fi calling which helps one connect with others even when there is low network coverage. Often it happens that while you are on a long phone call, suddenly your call drops and you see the message of ER081 error. 

How to fix this?

In this article, we will show you how to fix this frustrating problem. Even though, after the error has occurred, you can call back again to connect with whom were on call but fixing this problem will be better.

Check for Wi-Fi signals

If your Wi-Fi has a low signal your call may drop due to difficulty in connectivity issues. If you happen to move around during a call and reach a real low Wi-Fi signal area, your call quality will suffer, and might lose track of your network.

Switch to T-Mobile Router

If the above solution doesn’t work for you and you have a strong network and high-speed connection but still facing the ER081 error, you should go for T-Mobile CellSpot Router. It has been designed to support Wi-Fi calling, and as the router provides high bandwidth to the call, you can expect to get the best quality for Wi-Fi calling.

Solve the issue with your same router

Rather you can also use your regular Traffic manager and Quality of Service settings. As soon as you have got that router, you have to go to the Traffic Manager option and after that, you need to turn on the Quality of Service (QoS) rules and assure the primary/ first rule is listed as “4500” Protocol UDP and the secondary/ second rule is listed “5060, 5061” Protocol “TCP”. Also, don’t forget to permit at least 85% of the available bandwidth for Wi-Fi calling.

Power Cycle your router

Your router needs to be power cycled timely to keep the software and hardware module rejuvenated.

To power cycle your router, you need to switch off the power button and disconnect the plug, then plug in and switch it on after waiting for a minute.

Now you can test if it has worked or not by calling somebody and checking if the error still exists.
